Poster: Practical Trusted Computing for MHealth Sensing

Mobile sensing technologies present exciting opportunities for healthcare. Wireless sensors can automatically provide sensor data to care providers, dramatically improving their ability to diagnose, monitor, and manage a wide range of medical conditions. Using mobile phones to provide connectivity between sensors and providers is essential to keeping costs low and deployments simple. Unfortunately, software-based attacks against phones, which can have significant consequences for patients, are also on the rise. This poster describes a simple, flexible, and novel approach to protecting both the confidentiality and integrity medical sensing and data processing on vulnerable mobile phones, using plug-in smart cards - even a phone compromised by malware.
